re:shoulder tendonitis/bursitis

My name is Ramiro carreon.
I’m 14 years old and i have recurring shoulder tendonitis/bursitis. i went to therapy for 2 months and it went away for about a month but ever sice two weeks ago its came back. not as worst though. i work out regularly on a daily basis but only some of the exercises aggrevate the shoulder. i play baseball and i am a pitcher. before i got hurt i threw 80-85 mph since i’ve been hurt my velocity is very low. do you have any suggestions for me that dont involve therapy because my dad isn’t the most undertanding person. please reply to me as fast as ypu can thank you. 6/09/04
